Abstract
The present invention pertains to the provision of trimeric binding units which bind to trimeric cytokines. In particular there is provided a trimeric polypeptide comprising a trimerising domain and three monomers with binding members capable of binding a trimeric cytokine. Preferably , the trimeric binding units bind in a manner such that upon binding, all receptor binding sites of the trimeric cytokine are substantially blocked, and hence the potential biological activity of the trimeric cytokine is suppressed. In one aspect the invention relates to trimeric binders capable of binding to trimeric cytokines of the Tumor necrosis factor ligand superfamily, such as TNF, TRAIL, RANKL, TWEAK, APRIL and BAFF.
Description
Trimeric binding proteins for Trimeric Cytokines Field of the invention The present invention pertains to the provision of trimeric binding proteins which bind to trimeric cytokines. In particular there is provided trimeric binders that bind in a manner such that upon binding, all receptor binding sites of the trimeric cytokine are substantially blocked, and hence the potential biological activity of the trimeric cytokine is suppressed. In one aspect the invention relates to trimeric binders capable of binding to cytokines of the Tumour necrosis factor ligand superfamily, including tumour necrosis factor (TNF).
Background of the invention and prior art Cytokines are small secreted polypeptides from higher eukaryotes which are responsible for intercellular signal transduction and which affect the growth, division and functions of other cells. They are potent, pleiotropic polypeptides that, e.g. via corresponding receptors, act as local or systemic intercellular regulatory factors, and therefore play crucial roles in many biologic processes, such as immunity, inflammation, and hematopoiesis (formation and development of blood cells in the bone marrow). Cytokines are produced by diverse cell types including fibroblasts, endothelial cells, macrophages/monocytes, and lymphocytes. To date, a large number of cytokines have been identified, including interferons, tumour necrosis factors, interleukins and lymphokines. They differ from classical hormones in that they are produced by a number of tissues or cell types rather than by specialized glands.
The modulation of cytokine-receptor interactions can be a useful mechanism for therapeutic intervention in various diseases and pathologies. Soluble binding proteins, which can interact with cytokines, can potentially sequester the cytokine away from the receptor, thereby reducing or preventing the activation of that particular receptor pathway.
Certain cytokines occur as multi-subunit complexes containing multiple copies of the same subunit. Macrophage migration inhibitory factor (MIF) and proteins within the tumour necrosis factor ligand super family (TNFLSF), such as Tumour necrosis factor (TNF; TNFLSF member 2) and lymphotoxin alpha (LT-alpha; TNFLSF member 1 ), occur as homotrimers formed by three identical subunits. Many of these trimeric cytokines are known to be involved in signal transduction and to act as regulatory factors, and to be involved in many different types of diseases and medical indications.
The trimeric cytokines of the TNF ligand super family are known to control and orchestrate the immune and inflammatory responses at several levels. It is also known that TNF ligand super family members are associated with several disease conditions, such as acute or chronic inflammatory conditions. Presently, the TNF ligand super family has at least 17 recognised ligands, including LTA (lymphotoxin alpha;
TNFLSF
member 1 ), TNF (tumor necrosis factor; TNFLSF member 2), LTB (lymphotoxin beta;
TNFLSF member 3), OX-40L TNFLS member 4); CD40L (TNFLS member 5); Fast (TNFLS member 6); CD27L (TNFLS member 7); CD30L (TNFLS member 8); 4-1 BB-L
(TNFLS member 9); TRAIL (TNFLS member 10); RANKL (TNFLS member 11 );
TWEAK (TNFLS member 12); APRIL (TNFLS member 13); BAFF (TNFLS member 13B); LIGHT (TNFLS member 14); VEGI (TNFLS member 15); and GITRL (TNFLS
member 18).
Evidence exist that the signalling unit of the trimeric cytokines of the TNF
ligand super family and their corresponding receptors, is in the form of three receptors and three ligands assembled as a hexameric complex in which a single cytokine trimer binds to three receptor molecules (Bodmer et al. 2002, TRENDS in Biochemical Sciences 27(1 ), pp. 19-26). Before becoming part of this hexameric complex, the receptors exist in monomeric form. This general mechanism is illustrated in Figure 1.
TNF (TNFLSF member 2) is one of the principal mediators of the immune and inflammatory response, and it is e.g. known to have an important role in the pathogenesis of rheumatoid arthritis, which is a common autoimmune inflammatory disease that affects approximately 0.5-1 % of the human population.
Additionally, TNF
is also known to be involved in the pathogenesis of a wide range of disease states, including endotoxin shock, cerebral malaria and graft-versus-host reaction.
TNF is produced by a number of cell types, mainly by activated macrophages. The soluble form of TNF consists of three identical 17 kD protein subunits, whereas the membrane bound form consist of three identical 26 kD subunits. TNF is also previously known as "TNF-alpha" and "cachectin".
TWEAK (TNFLSF member 12) was recently found to be a direct and strong inducer of angiogenesis (formation and growth of blood vessels) as it was observed that picomolar concentrations of TWEAK promote proliferation of normal endothelial cells and that TWEAK induces angiogenesis in an in vivo rat cornea model (Lynch et al., 1999, The Journal of Biological Chemistry, 274(13) pp. 8455-8459). In particular angiogenesis is essential for the growth and persistence of solid tumours and their metastases, and it is also known to be involved in other pathological conditions such as diabetic retinopathy, psoriasis, contact dermatitis and restenosis.
In US20020037852A1 the trimeric cytokine BAFF (TNFLS member 13B) was described to be expressed by T cells and dendritic cells for the purpose of B-cell co-stimulation and consequently may play an important role in the control of B
cell function. It is suggested therein that BAFF and its receptor may have anti-cancer and immunoregulatory applications as well as uses for the treatment of immunosuppressive disorders such as HIV.
APRIL (TNFLS member 13) is a trimeric cytokine that binds to the receptor TNFRSF13B and to TNFRSF17. It has recently been shown that the addition of recombinant APRIL to various tumor cells stimulates their proliferation and hence APRIL may be implicated in the regulation of tumor cell growth (Hahne M., et al, 1998;
J. Exp. Med. 188:1185-1190). It has also been suggested that APRIL may be involved in monocyte/macrophage-mediated immunological processes.
Furthermore, cytokines within the TNF super family have also been described to be involved in hereditary diseases such as hyper IgM syndrome, type I autoimmune lymphoproliferative syndrome, TNF-R1-associated periodic fever syndrome, hypohidrotic ectodermal dysplasia and familial expansile osteolysis.

Soluble binding proteins, which can interact with cytokines, can potentially sequester the cytokine away from the receptor, thereby reducing or preventing the activation of that particular receptor pathway.
Certain cytokines occur as multi-subunit complexes containing multiple copies of the same subunit. Macrophage migration inhibitory factor (MIF) and proteins within the tumour necrosis factor ligand super family (TNFLSF), such as Tumour necrosis factor (TNF; TNFLSF member 2) and lymphotoxin alpha (LT-alpha; TNFLSF member 1 ), occur as homotrimers formed by three identical subunits. Many of these trimeric cytokines are known to be involved in signal transduction and to act as regulatory factors, and to be involved in many different types of diseases and medical indications.
The trimeric cytokines of the TNF ligand super family are known to control and orchestrate the immune and inflammatory responses at several levels. It is also known that TNF ligand super family members are associated with several disease conditions, such as acute or chronic inflammatory conditions. Presently, the TNF ligand super family has at least 17 recognised ligands, including LTA (lymphotoxin alpha;
TNFLSF
member 1 ), TNF (tumor necrosis factor; TNFLSF member 2), LTB (lymphotoxin beta;
TNFLSF member 3), OX-40L TNFLS member 4); CD40L (TNFLS member 5); Fast (TNFLS member 6); CD27L (TNFLS member 7); CD30L (TNFLS member 8); 4-1 BB-L
(TNFLS member 9); TRAIL (TNFLS member 10); RANKL (TNFLS member 11 );
TWEAK (TNFLS member 12); APRIL (TNFLS member 13); BAFF (TNFLS member 13B); LIGHT (TNFLS member 14); VEGI (TNFLS member 15); and GITRL (TNFLS
member 18).
Evidence exist that the signalling unit of the trimeric cytokines of the TNF
ligand super family and their corresponding receptors, is in the form of three receptors and three ligands assembled as a hexameric complex in which a single cytokine trimer binds to three receptor molecules (Bodmer et al. 2002, TRENDS in Biochemical Sciences 27(1 ), pp. 19-26). Before becoming part of this hexameric complex, the receptors exist in monomeric form. This general mechanism is illustrated in Figure 1.
TNF (TNFLSF member 2) is one of the principal mediators of the immune and inflammatory response, and it is e.g. known to have an important role in the pathogenesis of rheumatoid arthritis, which is a common autoimmune inflammatory disease that affects approximately 0.5-1 % of the human population.
Additionally, TNF
is also known to be involved in the pathogenesis of a wide range of disease states, including endotoxin shock, cerebral malaria and graft-versus-host reaction.
TNF is produced by a number of cell types, mainly by activated macrophages. The soluble form of TNF consists of three identical 17 kD protein subunits, whereas the membrane bound form consist of three identical 26 kD subunits. TNF is also previously known as "TNF-alpha" and "cachectin".
TWEAK (TNFLSF member 12) was recently found to be a direct and strong inducer of angiogenesis (formation and growth of blood vessels) as it was observed that picomolar concentrations of TWEAK promote proliferation of normal endothelial cells and that TWEAK induces angiogenesis in an in vivo rat cornea model (Lynch et al., 1999, The Journal of Biological Chemistry, 274(13) pp. 8455-8459). In particular angiogenesis is essential for the growth and persistence of solid tumours and their metastases, and it is also known to be involved in other pathological conditions such as diabetic retinopathy, psoriasis, contact dermatitis and restenosis.
In US20020037852A1 the trimeric cytokine BAFF (TNFLS member 13B) was described to be expressed by T cells and dendritic cells for the purpose of B-cell co-stimulation and consequently may play an important role in the control of B
cell function. It is suggested therein that BAFF and its receptor may have anti-cancer and immunoregulatory applications as well as uses for the treatment of immunosuppressive disorders such as HIV.
APRIL (TNFLS member 13) is a trimeric cytokine that binds to the receptor TNFRSF13B and to TNFRSF17. It has recently been shown that the addition of recombinant APRIL to various tumor cells stimulates their proliferation and hence APRIL may be implicated in the regulation of tumor cell growth (Hahne M., et al, 1998;
J. Exp. Med. 188:1185-1190). It has also been suggested that APRIL may be involved in monocyte/macrophage-mediated immunological processes.
Furthermore, cytokines within the TNF super family have also been described to be involved in hereditary diseases such as hyper IgM syndrome, type I autoimmune lymphoproliferative syndrome, TNF-R1-associated periodic fever syndrome, hypohidrotic ectodermal dysplasia and familial expansile osteolysis.
Several attempts have been made in order to find and develop suitable antagonists and binders for trimeric cytokines which are capable of binding to specific trimeric cytokines and thereby preventing the trimeric cytokines from binding to e.g.
cell membrane bound receptors and hence suppressing the activation of that particular receptor pathway.
One example is antagonists against the trimeric cytokine TNF (TNFLSF member 2).
Presently, two types of TNF antagonists are commercially available, namely Infliximab (Remicade) and Eternarcept (Enbrel) which have both received marketing authorization in the United States and Europe for treatment of rheumatoid arthritis. The two products have also been shown to be effective for the treatment of psoriasis and Chrohn's disease. Infliximab is a chimeric antibody with murine variable regions and human IgG1 and ? constant regions, which neutralizes the biological activity of TNF by binding to the soluble and transmembrane forms of TNF and inhibits the binding of TNF with its receptors. The structure of Infliximab is similar to that of naturally occurring antibodies. Eternacept is a fusion protein made up of the extracellular domain of the p75 TNF receptor and the hinge and Fc domains of human IgG1.
Another example of an antagonist for a trimeric cytokine is given in WO
where a monoclonal antibody against the trimeric cytokine TWEAK (TNFLS member 12) is disclosed. It is mentioned that the antibody can block the development of Graft-Versus-Host Disease.
However, a common technical problem that is encountered with the presently known binders and inhibitor products for trimeric cytokines, is that upon formation of a 1:1 complex of the trimeric cytokine and the binder or inhibitor product, not all three receptor binding sites of the trimeric cytokines are effectively blocked, as at least one or two of the three receptor binding sites are left open. The open cytokine receptor binding sites) may associate with a corresponding cell surface cytokine receptor and thereby, due to high local concentration of the receptors on the cell surface, initiate the further recruitment of cytokine receptors and mediate receptor signalling.
cell membrane bound receptors and hence suppressing the activation of that particular receptor pathway.

The open cytokine receptor binding sites) may associate with a corresponding cell surface cytokine receptor and thereby, due to high local concentration of the receptors on the cell surface, initiate the further recruitment of cytokine receptors and mediate receptor signalling.
The problem is clearly illustrated by the TNF binder Eternacept, which is a bivalent molecule that forms a 1:1 complex with the TNF trimer. When Eternacept binds to TNF, only two out off three possible receptor binding sites are occupied by the Eternacept molecule, and the third receptor binding site is left open. This implies that the open TNF receptor binding site may associate with a cell surface TNF
receptor and thereby, due to high local concentration of the receptors on the cell surface, initiate the further recruitment of TNF receptors and by that signal transduction. This problem is illustrated in Figure 2.
The same problem is seen with the TNF binder Infliximab. Each Infliximab molecule is only capable of binding one receptor binding site (subunit) of a given TNF
molecule, hence leaving out two open receptor binding sites. These open receptor binding sites may subsequently associate with corresponding free receptors, resulting in further recruitment of TNF receptors and receptor signalling.
It has now been found by the present inventors, that the above technical problems may be overcome by the provision of a fusion protein (protomer) which is constructed as a fusion of a binding unit (binder) for trimeric cytokines to a trimerising domain. The fusion protein of the present invention is, as a trimeric protein, capable of forming a 1:1 complex with a trimeric cytokine and preferably at the same time effectively binding all three receptor binding sites of the trimeric cytokines, whereby no receptor binding sites are left open, and is therefore able to inhibit docking of the cytokine to the cell surface.
Thus, there is now provided a fusion protein which has the advantage of being capable of more effectively inhibiting and neutralising the biological activity of trimeric cytokines as compared to presently known trimeric cytokine antagonists. A further advantage of the fusion protein according to the invention is that when applied as a medicament, less amount of the fusion protein is required in order to obtain a therapeutic effect, as compared to the presently know binders for trimeric cytokines.
Summary of the invention Accordingly, the invention relates in a first aspect to a trimeric polypeptide comprising three monomers, each of said monomers comprising a specific binding member capable of binding a trimeric cytokine, and each of said monomers comprising a trimerising domain.
In a further aspect there is provided a pharmaceutical composition comprising the trimeric polypeptide according to the invention.
In a still further aspect, the invention pertains to a method of treating a subject having a pathology mediated by a trimeric cytokine such as tumour necrosis factor, by administering an effective amount of the trimeric polypeptide according to the invention to the subject, Finally, there is provided a method for the preparation of the trimeric polypeptide according to invention, and an assay method for detecting a trimeric polypeptide cytokine in a sample.
Detailed disclosure of the invention In one aspect, the present invention provides trimeric binders which are capable of binding to trimeric cytokines, preferably in a manner such that upon binding, all receptor binding sites of the trimeric cytokine are substantially blocked and/or neutralised, and hence the potential biological activity of the trimeric cytokine is suppressed or neutralised. Accordingly, there is provided a trimeric polypeptide comprising three monomers, wherein each of the monomers comprise a specific binding member which is capable of binding a trimeric cytokine, and wherein each of the monomers comprise a trimerising domain.
In the present context, the term "trimeric cytokine" refers to small proteins and fragments thereof, which are produced and secreted by a cell, and which elicit a specific response in a cell which has a receptor for that cytokine, e.g. by affecting the growth, division and/or function of the cell. The term "trimeric" is used herein to describe that the cytokines according to the invention occur as multi-subunit complexes containing three subunits, preferably three identical subunits (homotrimer).
Typical examples of such trimeric cytokines include Macrophage migration inhibitory factor (MIF) and cytokines within the tumour necrosis factor ligand super family (TNFLSF). Presently, as mentioned above, the TNF ligand super family has at least 17 recognised ligands which all share a conserved trimeric C-terminal domain known as the "TNF homology domain" (THD), which is responsible for receptor binding.
The sequence identity of this trimeric domain is approximately 20-30% between TNF
family members. The THD is a 150 amino acid long sequence containing a conserved framework of aromatic and hydrophobic residues which is illustrated in Figure 2 in Bodmer et al. 2002, TRENDS in Biochemical Sciences 27(1 ), pp. 19-26.
Accordingly, in the present context a "member of the Tumor necrosis factor ligand superfamily" is intended to mean a trimeric protein comprising the TNF homology domain, THD.

The term "specific binding member", as used herein, refers to a member of a pair of molecules which have binding specificity for one another. The members of a specific binding pair may be naturally derived or wholly or partially synthetically produced. One member of the pair of molecules has an area on its surface, or a cavity, which specifically binds to and is therefore complementary to a particular spatial and polar organisation of the other member of the pair of molecules. Thus the members of the pair have the property of binding specifically to each other. Examples of types of specific binding pairs are antigen-antibody, biotin-avidin, hormone-hormone receptor, ligand-ligand receptor, enzyme-substrate. Other examples of specific binding pairs include, carbohydrates and lectins, complementary nucleotide sequences (including probe and capture nucleic acid sequences used in DNA hybridization assays to detect a target nucleic acid sequence), complementary peptide sequences including those formed by recombinant methods, effector and receptor molecules, enzyme cofactors and enzymes, enzyme inhibitors and enzymes, and the like. Furthermore, specific binding pairs can include members that are analogues or fragments of the original specific binding member.
In useful embodiments, the specific binding members capable of binding a trimeric cytokine, provides the trimeric polypeptide according to the invention with a binding affinity (Kd) for the trimeric cytokine that preferably is 1 x 10-$ M or less determined by surface plasmon resonance. In other useful embodiments, the Kd value is less than 1 x 10-9 M, 1 x 10-'° M, 1 x 10-" M, 1 x 10-'2 M, 1 x 10-'3 M, 1 x 10-'4 M, or even less than 1 X 1 O-'S M. In further useful embodiments, the K-off rate for the trimeric polypeptide according to the invention is less than 1 x 10-3 S-', such as less than 1 x 10-4 S'', including less than 1 x 10-5 S-', and even less than 1 x 10-6 S-' determined by surface plasmon resonance. The term "K-off', as used herein, is intended to refer to the off rate constant for dissociation of a specific binding member from the specific binding member/trimeric cytokine complex. The term "surface plasmon resonance", as used herein, refers to an optical phenomenon that allows for the analysis of real-time biospecific interactions by detection of alterations in protein concentrations within a biosensor matrix, for example using the BIAcore system (Pharmacia Biosensor AB, Uppsala, Sweden). For further descriptions, see Example 10.
As mentioned above, it is preferred that the trimeric cytokine binder according to the invention at least partially or fully blocks, inhibits, or neutralises a biological activity of a trimeric cytokine. As used herein, the expression "neutralises" or "neutralisation"
means the inhibition of or reduction in a biological activity of a trimeric cytokine as measured in vivo or in vitro.
In useful embodiments the specific binding member is a polypeptide derived from a member of the Tumor necrosis factor receptor superfamily. Presently, at least receptors within the Tumor necrosis factor superfamily are known, and listed below in Table 2 together with their synonyms and their corresponding Genbank ID
(GenBank, National Center for Biotecnology Information;

Thus, in useful embodiments the specific binding member derived from a receptor within the Tumor necrosis factor superfamily is selected from the receptors TNFRSF1A, TNFRSF1B, LTBR, TNFRSF4, TNFRSFS, TNFRSF6, TNFRSF6B, TNFRSF7, TNFRSFB, TNFRSF9, TNFRSF10A, TNFRSF10B, TNFRSF10C, TNFRSF10D, TNFRSF11A, TNFRSF11B, TNFRSF12, TNFRSF12L, TNFRSF13B, TNFRSF13C, TNFRSF14, NGFR, TNFRSF17, TNFRSF18, TNFRSF19, TNFRSF19L, TNFRSF21, TNFRSF22, and TNFRSF23. However, it is also contemplated that further useful receptors may be identified within this protein family, and hence further functional specific binding members.
In a useful embodiment, the specific binding member is derived from the TNF
receptors TNFRSF1A (TNFrI, p55 receptor) and/or TNFRSF1 B (TNFrI I, p75 TNF
receptor). Especially the TNFRSF1 B receptor and subunits thereof has proven to be effective for specifically binding and neutralising TNF. As an example, the TNF binding protein Eternacept is a fusion protein made up of the extracellular domain of the TNFRSF1 B receptor, i.e. a subunit of the TNFRSF1 B receptor. Accordingly, in specific embodiments, the trimeric polypeptide according to invention includes a specific binding member which is a subunit or fragment of the TNFRSF1 B receptor (TNFrII), such as the TNFRSF1 B receptor fragments disclosed in US 5,712,155. Thus, in useful embodiments the specific binding member is a polypeptide comprising an amino acid sequence selected from TNFRSF1B 1-235 (SEQ ID N0:76), TNFRSF1B 1-185 (SEQ
ID N0:77), TNFRSF1B 1-163 (SEQ ID N0:78) and TNFRSF1B 1-142 (SEQ ID
N0:79).
In further useful embodiments, as disclosed in following examples, the specific binding member may be one or more fragments of the TNFRSF1 B receptor (TNFrII) and combinations of such fragments, such as a polypeptide comprising an amino acid sequence encoded by a DNA sequence selected from TNFRSF1 B D1 D2 (SEQ ID
N0:13), TNFRSF1 B D1 D2, 1/6 (SEQ ID N0:15), TNFRSF1 B D1 D2 1/4 (SEQ ID
N0:17), TNFrII D1 D2, 1/3 (SEQ ID N0:19), TNFRSF1 B D1 D2, 1/2 (SEQ ID N0:21 ), TNFRSF1 B D1 D4 (SEQ ID N0:23), TNFRSF1 B D2 (SEQ ID N0:25), TNFRSF1 B D2, 1/6 (SEQ ID N0:26), TNFRSF1B D2, 1/4 (SEQ ID N0:27), TNFRSF1B D2, 1/3 (SEQ
ID N0:28), TNFRSF1B D2, 1/2 (SEQ ID N0:29) and TNFRSF1B D2D4 (SEQ ID
N0:30).
In accordance with the invention, the specific binding member capable of binding a trimeric cytokine may also be an antibody or an antibody fragment. In the present context, the term "antibody" is used to describe an immunoglobulin whether natural or partly or wholly synthetically produced. As antibodies can be modified in a number of ways, the term "antibody" should be construed as covering any specific binding member or substance having a binding domain with the required trimeric cytokine specificity. Thus, this term covers antibody fragments, derivatives, functional equivalents and homologues of antibodies, including any polypeptide comprising an immunoglobulin binding domain, whether natural or wholly or partially synthetic.
Chimeric molecules comprising an immunoglobulin binding domain, or equivalent, fused to another polypeptide are therefore included. The term also covers any polypeptide or protein having a binding domain which is, or is homologous to, an antibody binding domain, e.g. antibody mimics. These can be derived from natural sources, or they may be partly or wholly synthetically produced. Examples of antibodies are the immunoglobulin isotypes and their isotypic subclasses;
fragments which comprise an antigen binding domain such as Fab, scFv, Fv, dAb, Fd; and diabodies.
US 6,451,983 B2 describes antibodies for human tumour necrosis factor which are i.a.
capable of neutralising the biological activity of TNF. In particular, US
6,451,983 B2 provides antibodies and fragments thereof which are capable of binding to mature human TNF (SEQ ID N0:80) within certain specific topographic regions.
Accordingly, in useful embodiments of the present invention, the specific binding member is an antibody or fragment thereof which is capable of binding mature human TNF (SEQ
ID
N0:80) in at least one region selected from the regions consisting of amino acid residues 1-18, 1-20, 1-26, 1-30, 12-22, 22-31, 22-40, 36-45, 49-97, 49-98 , 56-79, 58-65, 69-97, 70-87, 76-90, 96-105, 105-128, 108-128, 110-127, 115-125, 117-128, 157, 135-155, 136-153, 138-149, 141-153 and 146-157.
US 6,451,983 B2 further provides specific monoclonal antibodies which may be useful in the present invention. Accordingly, the specific binding member capable of binding human TNF may be an antibody or antibody fragment selected from MAb 1 (ECACC
89080301 ), MAb 21 (ECACC 90012432), MAb 25 (ECACC 89121401 ), MAb 32 (ECACC 89080302), MAb 37 (ECACC 89080303), MAb 42 (ECACC 89080304), MAb 47 (ECACC 89121402), MAb 53 (ECACC 90012433) and MAb 54 (ECACC
89083103), wherein ECACC refers to European Collection of Animal Cell Cultures.
Further examples of useful antibodies include the humanised antibody D2E7 as disclosed in US 6,090,382 and the humanised antibody fragment CDP 870 as disclosed in WO/00194585.
In specific embodiments, the specific binding members of the present invention may comprise antibody analogues or artificial antibodies such as e.g. a protein having the scaffold structure of C-type lectin-like domains (CTLD) as disclosed in WO/0248189.
As will be apparent from the following Examples, useful human tetranectin based CTLD antibody analogues which are capable of binding TNF may be selected from TN3-2-B (SEQ ID N0:103), TN3-2-C (SEQ ID N0:104) and TN3-2-D (SEQ ID
N0:105).
An important aspect of the present invention is that the monomers of the trimeric polypeptide, in addition to the specific binding member, further comprise a trimerising domain. In the present context, the term "trimerising domain" is a peptide, a protein or part of a protein which is capable of interacting with other, similar or identical trimerising domains. The interaction is of the type that produces trimeric proteins or polypeptides. Such an interaction may be caused by covalent bonds between the components of the trimerising domains as well as by hydrogen bond forces, hydrophobic forces, van der Waals forces and salt bridges.
One example of a trimerising domain is disclosed in WO 95/31540, which describes polypeptides comprising a collectin neck region. The amino acid sequence constituting the collectin neck region may be attached to any polypeptide of choice.
Trimers can then be made under appropriate conditions with three polypeptides comprising the collectin neck region amino acid sequence.
In a presently preferred embodiment, the trimerising domain is derived from tetranectin, and more specifically comprises the tetranectin trimerising structural element (hereafter termed TTSE) which is described in detail in WO 98/56906.
The amino acid sequence of TTSE is shown in SEQ ID N0:81. The trimerising effect of TTSE is caused by a coiled coil structure which interacts with the coiled coil structure of two other TTSEs to form a triple alpha helical coiled coil trimer which is exceptionally stable even at relatively high temperatures. The term TTSE is also intended to embrace variants of a TTSE of a naturally occurring member of the tetranectin family of proteins, variants which have been modified in the amino acid sequence without adversely affecting, to any substantial degree, the capability of the TTSE to form alpha helical coiled coil trimers. Thus, the trimeric polypeptide according to the invention may comprise a TTSE as a trimerising domain, which comprises a sequence having at least 68% amino acid sequence identity with the sequence of SEQ ID NO SEQ ID N0:81, such as at least 75%, including at least 87%, such as at least 92%. In accordance herewith, the cystein residue No. 50 of the TTSE (SEQ ID N0:81 ) may advantageously be mutagenised to serine, threonine, methionine or to any other amino acid residue in order to avoid formation of an unwanted inter-chain disulphide bridge, which could lead to unwanted multimerisation.
In a further embodiment, the TTSE trimerising domain (SEQ ID N0:81 ) may be modified by (i) the incorporation of polyhistidine sequence and/or a cleavage site for the Blood Coagulating Factor Xa, (ii) replacing Cys 50 with Ser, and (iii) by including a C-terminal KGS sequence.
Several examples of different trimeric polypeptides in accordance with the invention are provided in the following in examples, in which the above TTSE trimerising domain has been applied. These includes i.a. the CTLD based TNF binding units TN-2-B
(SEQ
ID N0:106), TN-2-C (SEQ ID N0:108) and TN-2-D (SEQ ID N0:107), and the trimerised human TNFRII fragment AD1 D4-GSS-110 (SEQ ID N0:109).
In accordance with the invention, the specific binding member may either be linked to the N- or the C-terminal amino acid residue of the trimerising domain.
However, it is also envisaged that in certain embodiments it may be advantageous to link a specific binding member to both the N-terminal and the C-terminal of the trimerising domain of the monomer, and thereby providing a trimeric polypeptide comprising six specific binding members capable of binding a trimeric cytokine.
It will be appreciated that a flexible molecular linker optionally may be interposed between, and covalently join, the specific binding member and the trimerising domain.
In certain embodiments, the linker is a polypeptide sequence of about 1-20 amino acid residues. The linker may be less than 10 amino acids, most preferably, 5, 4, 3, 2, or 1.
It may be in certain cases that 9, 8, 7 or 6 amino acids are suitable. In useful embodiments the linker is essentially non-immunogenic, not prone to proteolytic cleavage and does not comprise amino acid residues which are known to interact with other residues (e.g. cystein residues).
The trimeric polypeptide of the present invention may be expressed in any suitable standard protein expression system by culturing a host transformed with a vector encoding the trimeric polypeptide under such conditions that the trimeric polypeptide is expressed. Preferably, the expression system is a system from which the desired protein may readily be isolated and refolded in vitro. As a general matter, prokaryotic expression systems are preferred since high yields of protein can be obtained and efficient purification and refolding strategies are available. Thus, it is well within the abilities and discretion of the skilled artisan, without undue experimentation, to choose an appropriate or favourite expression system. Similarly, once the primary amino acid sequence for the trimeric polypeptide of the present invention is chosen, one of ordinary skill in the art can easily design appropriate recombinant DNA
constructs which will encode the desired proteins, taking into consideration such factors as codon biases in the chosen host, the need for secretion signal sequences in the host, the introduction of proteinase cleavage sites within the signal sequence, and the like.
These recombinant DNA constructs may be inserted in-frame into any of a number of expression vectors appropriate to the chosen host. The choice of an appropriate or favourite expression vector is, again, a matter well within the ability and discretion of the skilled practitioner. Preferably, the expression vector will include a strong promoter to drive expression of the recombinant constructs. Finally, the trimeric polypeptide may be isolated using suitable standard procedures well known in the art, and optionally subjected to further processing such as e.g. lyophilization.
The trimeric polypeptide according to the invention may be used for the preparation of a pharmaceutical composition by any suitable method well known in the art. The composition may together with the trimeric polypeptide, comprise one or more acceptable carriers therefore, and optionally other therapeutic ingredients.
The carriers must be acceptable in the sense of being compatible with the other ingredients and not deleterious to the recipient thereof. In general, methods for the preparation of pharmaceutical compositions include the step of bringing into association the active ingredient and a carrier.
The therapeutic application of the present invention comprises the treatment of a disease or disorder in an animal, by administering a therapeutically effective amount of the trimeric polypeptide according to the invention to an animal in need thereof. As mentioned above, trimeric cytokines, and in particular trimeric cytokines of the TNF
ligand super family, are known to be pleiotropic polypeptides that act as intercellular signal transduction molecules by i.a. controlling and coordinating immune and inflammatory responses. Thus, it will be appreciated that the trimeric polypeptide of the present invention may be applicable for the treatment of wide range of disorders and diseases mediated by trimeric cytokines, including inflammatory diseases, autoimmune disorders, immune disorders, infections, malignancies, and neurogenerative diseases.
In one useful embodiment the disease is a pathology mediated by tumor necrosis factor, such as rheumatoid arthritis, psoriasis and Crohn's disease.
The trimeric polypeptide of the present invention may be directly administered to the animal by any suitable technique, including parenterally, and can be administered locally or systemically. The specific route of administration depends, e.g., on the medical history of the animal. Examples of parenteral administration include subcutaneous, intramuscular, intravenous, intraarterial, and intraperitoneal administration.
The animals potentially treatable by the trimeric fusion protein herein include mammals such as a human.
Finally, the present invention provides an assay method for detecting a trimeric polypeptide cytokine in a sample which comprises (i) contacting the sample with a trimeric polypeptide according to the invention, and (ii) detecting the binding of the trimeric polypeptide to the trimeric cytokine.
The invention will now be described by way of illustration in the following non-limiting examples and figures.
Description of the figures Figure 1 shows the binding of a trimeric cytokine within the Tumour Necrosis Factor Super Family to a corresponding cell bound monomeric receptor, which initiates the further recruitment of two more cytokine receptors resulting in the formation of a hexameric cytokine-receptor signalling unit.
Figure 2 shows the binding of a bivalent binder to a trimeric cytokine within the Tumour Necrosis Factor Super Family (TNFSF), which forms a 1:1 complex with the trimeric cytokine. When the bivalent binder binds to the trimeric TNFSF
cytokine, only two out off three possible receptor binding sites are occupied by the bivalent binder molecule, and the third receptor binding site is left open. This implies that the open trimeric cytokine receptor binding site may associate with a cell surface trimeric cytokine receptor and thereby, due to high local concentration of the receptors on the cell surface, initiate the further recruitment of trimeric receptors and thereby signal transduction.
Figure 3 shows a binder for trimeric cytokines which is capable of forming a 1:1 complex with a trimeric cytokine and at the same time effectively binding all three receptor binding sites of the trimeric cytokine, whereby no receptor binding sites are left open. The docking of the cytokine to the cell surface is blocked, and hence no signal transduction will occur.
Figure 4 shows inhibition of TNF alpha mediated cytotoxicity in a murine fibroblast cell line L929 assay at two different fixed TNF alpha concentrations (1.0 ng/ml and 0.1 ng/ml) for the trimerised receptorfragment D1 D4GSS110 Trip in 10-fold dilutions.

Example 3 Production, refolding and purification of trimerised TNFRII fragment AD1 D4-GSS-110-TripB
Construction of the T7 RNA polymerise dependent expression plasmid pT7D1 D4GSS110 (expressing the TNFRII derivative AD1 D4-GSS-110-TripB) is described above in Example 2.
Trimerised human TNFRII fragment AD1 D4-GSS-110 (SEQ ID N0:109) was produced by growing and expressing the plasmid pT7AD1 D4-GSS-110 in E. coli BL21 cells in a medium scale (6 x 1 litre) as described by Studier and Moffat, J. Mol. Biol., 189:
113-130, 1986. Briefly, exponentially growing cultures at 37°C were at OD600 0.8 infected with bacteriophage ~-CE6 at a multiplicity of approximately 5.
Cultures were grown at 37°C for another three hours before cells were harvested by centrifugation.
Cells were lysed by osmotic shock and sonification and total cellular protein extracted into phenol (adjusted to pH 8 with Trisma base). Protein was precipitated from the phenol phase by addition of 2.5 volumes of ethanol and centrifugation. The protein pellet was dissolved in a buffer containing 6 M Guanidinium chloride, 50 mM
Tris-HCI
pH 8 and 50 mM dithioerythriol. Following gel filtration on Sephadex G-25 (Amersham Biosciences) into 8 M Urea, 0.5 M NaCI, 50 mM Tris-HCI pH 8, and 5 mM 2-mer-captoethanol the crude protein preparation was applied to Ni2+ activated NTA-agarose (Qiagen, Germany) columns for purification (Hochuli et al., 1988) of the fusion proteins and, while immobilised on the column, to undergo the cyclic folding procedure as previously described in WO 94/18227.
All buffers prepared for liquid chromatography were degassed under vacuum prior to addition of reductant and/or use.
Upon application of the crude protein extracts on the Ni2+NTA-agarose column, the fusion protein, AD1 D4-GSS-110, was purified from the majority of coli and ~
phage proteins by washing with one column volume of the loading buffer followed by 6 M
Guanidinium chloride, 50 mM Tris-HCI, and 5 mM 2-mercaptoethanol until the optical density (OD) at 280 nm of the column eluate was stable.
The fusion proteins were refolded on the Ni2+NTA-agarose column using a gradient manager profile as described in Table 1 and 0.5 M NaCI, 50 mM Tris-HCI pH 8, and 2 mM/0.2 mM reduced/oxidized gluthatione as buffer A and 8 M urea, 0.5 M NaCI, mM Tris-HCI pH 8, and 3 mM reduced gluthatione as buffer B.
After completion of the cyclic folding procedure the AD1 D4-GSS-110 fusion protein was eluted from the Ni2+NTA-agarose columns with a buffer containing 8 M Urea, 0.5 M
NaCI, 50 mM Tris-HCI, and 10 mM EDTA pH 8.
Monomeric AD1 D4-GSS-110 fusion proteins were purified from di-mer and higher order multimers by ion exchange chromatography on S- and Q-Sepharose (AmershamBiosciences): The fusion protein eluted by the elution buffer (approximately 80 % of the fusion protein material) was gelfiltrated into a buffer containing 8 M Urea, mM Tris-HCI pH 8.0 and 25 mM NaCI on Sephadex G-25 and applied onto the S-Sepharose ion exchange column. The non-binding protein in the "run through"
fractions were directly loaded onto the Q-Sepharose column. Monomeric AD1 D4-GSS-110 fusion proteins were eluted from the Q-Sepharose column with a liner gradient from 8 M Urea, 25 mM NaCI, 10 mM Tris-Hcl pH 8 to 8 M Urea, 300 mM NaCI, 10 mM
Tris-Hcl pH 8 over 10 column volumes. Monomeric AD1 D4-GSS-110 fusion protein eluted in the very beginning of the gradient, whereas dimers and higher order multimers eluted later. Fractions containing the monomeric fusion protein were renatured and trimerised by gelfiltration into a buffer containing 10 mM HEPES
pH 7.4 and 125 mM NaCI.

The murine fibroblast cell line L929 (ECACC no.: 85011425) was used to measure TNF alpha mediated cytotoxicity. Cells were maintained in RPMI 1640 liquid medium (Biowhittaker, UK) supplemented with 10% FBS, and antibiotics (100 U/ml penicillin, 100 Ng/ml streptomycin). The cells were plated into 96-well flat-bottom microtiter plates (NUNC, Roskilde, Denmark) at 3 x 105 cells/ml and 75 NI/well of complete RPMI
1640 medium and cultured overnight at 37°C in 5% C02. Recombinant human TNF
alpha (rhTNFa, RD Systems, UK) (1 ng/ml and 0.1 ng/ml) was incubated with various concentrations (10-fold dilutions) of trimerised receptorfragment (AD1 D4-GSS-110) in complete RPMI 1640 medium supplemented with 2 pg/ml actinomycin D (Sigma) for hr at 37°C in 5% C02. Hereafter, 75 NI/well of the TNF-alpha/trimerised receptorfragment mixtures were added to the cell culture for overnight incubation at 37°C in 5% C02. Each concentration of the TNF-alpha / receptorfragment mixture was tested in triplicate. Cell proliferation was determined using MTT (3-[4,5-dimethyl-thiazol-2-yl]-2,5-di-phenyl-tetrazolium bromide) as part of the CeIITiter 96 Non-Radioactive Cell Proliferation Assay Kit (Promega). For the preparation of reagents sufficient for one 96 well plate containing cells cultured in a 150 pl volume, 3.0 ml of MTS Solution was added to 150 NI of PMS. 30 NI/well of the combined MTS/PMS
solution was added and the plates were incubated 1-4 hr at 37°C in 5%
C02 before recording the absorbance at 492 nm using an ELISA plate reader. Controls of TNF
alpha with the cells, cells alone and buffer control were also included in each assay.
The result of the experiment is summarised in Fig. 4. The cytotoxic effect of TNF alpha was significantly inhibited in the presence of the highest concentration of 110 thus demonstrating biological activity of the compound.

To prepare the above fusion proteins H6FXD2E7tripB, H6FXD2E7G4StripB, H6FXTripAD2D7TripA and H6FxTripAG4SD2E7, the plasmids pT7H6FXD2E7tripB, pT7H6FXD2E7G4StripB, pT7H6FXTripAD2D7TripA and pT7H6FxTripAG4SD2E7 is grown in small scale (1 litre; 2xTY medium, 5 mM MgS04 and 100 4 g ampicillin) in E.
coli BL21 cells, as described by Studier et al. (1990). Exponentially growing cultures at 37°C are at OD600 0.8 infected with bacteriophage lambda CE6 at a multiplicity of approximately 5. Cultures are grown at 37°C for another three hours and the cells harvested by centrifugation. Cells are re-suspended in 50 ml of 0.5 M NaCI, 50 mM
Tris-HCI pH 8, and 1 mM EDTA pH 8. Phenol (50 ml adjusted to pH 8) is added to each and the mixtures are sonicated to extract total protein. After clarification by centrifugation (25 minutes at 10.000 g) crude protein fractions are precipitated from the phenol phases by addition of 2.5 volumes of ethanol and centrifugation.
Protein pellets are dissolved in a buffer (15-25 ml) containing 6 M guanidinium chloride, 50 mMTris-HCI pH 8 and 0.1 M dithioerythriol. Following gel filtration on Sephadex G-25 (Pharmacia, Sweden) into 8 M Urea, 1 M NaCI, 50 mM Tris-HCI pH 8 and 10 mM 2-mercaptoethanol, the crude protein preparations are applied to Ni activated NTA-agarose columns (75 ml column volume) for purification (Hochuli et al., 1988).
Washing buffer (6 M guanidine-HCI, 50 mM Tris-HCI pH 8 and 10 mM 2-mercaptoethanol) is then flowed through the columns until stable baselines are obtained.
Virtually pure fusion proteins are then eluted by applying a pH gradient to each column (1000 ml gradient in 8 M urea and 10 mM 2-mercaptoethanol obtained by linear (per volume) mixing of solutions containing 50 mM sodium di-hydrogenphosphate (pH 5 buffer) and 50 mM di-sodium hydrogenphosphate (pH 8 buffer).
In preparation for in vitro refolding by the method of Thogersen et al. (WO
94/18227) 20 mg of each purified fusion protein are mixed in suspensions in refolding "buffer B"
(described below) with aliquots of suspensions of Ni2+ activated NTA-agarose matrix sufficient to generate columns of about 75 ml packed bed volume. Each fusion protein is then subjected to the iterative refolding procedure as described for plasminogen kringle 4 in WO 94/18227, except that refolding of the scFv containing fusion proteins is carried out at 10°C using a buffer containing 0.5 M NaCI, 50 mM Tris-HCI pH 8, 2 mM glutathione and 0.2 mM oxidized glutathione as "buffer A" and a buffer containing 8 M urea, 1 M NaCI, 50 mM Tris-HCI pH 8 and 2 mM glutathione as "buffer B".
After completion of the refolding procedure each column is washed with 300 ml buffer containing 0.5 M NaCI and 50 mM Tris-HCI pH 8 to wash away glutathione. The refolded fraction of each protein is then eluted from the NTA-agarose in 20 mM
EDTA, 0.5 M NaCI and 50 mM Tris-HCL pH 8 to the elution buffer. After addition of solid urea to achieve a final concentration of about 8 M to each protein sample and dilution or dialysis to reduce NaCI concentrations to below 5 mM, final purification of each correctly folded fusion protein product is then accomplished by ion exchange chromatography (S-Sepharose, Pharmacia, 1,6 (i.d.) by 90 centimeter column in a buffer containing 8 M urea, 5 mM Tris-HCI (from 1 M stock solution at pH 8) and 25 mM sodium acetate (from 1 M stock solution at pH 5), eluted at 2 ml/min).
After dialysis against aqueous buffers (e.g. phosphate buffered saline) each pure and correctly refolded fusion protein is recovered in yields of 2-6 mg per litre of culture grown.

Example 9 Isolation and construction of trimerised CTLD binders for TNF
The scaffold structure of Tetranectin (SEQ ID N0:96) C-type lectin-like domains (CTLD), as previously disclosed in WO/0248189, was used for the isolation and construction of a trimeric binding units for the trimeric cytokine TNF (TNF
alpha). The design and cloning of the binding units is outlined in the following:
Library construction and primary selection Phage display was used to isolate TNF CTLD binders. The phage display libraries used were based on the monovalent CTLD format of tetranectin (SEQ ID N0:97).
The combinatorial library PhtCTLD-Ib003 (WO/0248189, Example 5) and a variant of this library made essential as PhtCTLD-Ib003, but including two additional randomised oligonucleotides for loop 1: TN-lib3-tprev, randomised in tetranectin (SEQ ID
N0:98) amino acid residue positions 116-122 and TN-lib2-tprev (SEQ ID NO: 99) and 2 additional oligonucleotides for loop 4: TN-lib3-tpfo, randomised in position (SEQ ID N0:100) and TN-lib2-tpfo (SEQ ID N0:101 ) in the assembly reaction.
Two rounds of selection were performed using approximately 1 x 10'2 phage as input and Ng/ml biotinylated-TNF in the first round of panning and 1 Ng/ml in the second.
The selections were performed as follows: 20 NI streptavidin-coated paramagnetic beads (Dynal) were washed two times in 1 ml PBS (PBS, 0.2 g KCI, 0.2 g KH2P04, 8 g NaCI, 1.44 g Na2HP04, 2H20, water to 1 I, and adjusted to pH 7.4 with NaOH), and blocked in 3% non fat dried milk for one hour at room temperature. 250 NI
preblocked phage in 3% non fat dried milk/PBS were mixed with 250 NI of soluble biotinylated TNF, and allowed to incubate at 37°C for 30 minutes. After washing the streptavidin beads once in PBS, 0.1 % Tween 20 and twice in PBS, these were added to the reaction to capture antigen-bound phage. The beads were extensively washed with PBS, 0.1 % Tween 20 and PBS, and antigen bound phage were eluted from the beads with 200 NI 50 mM dithiothreitol for 30 min at room temperature. Eluted phages were reinfected in exponentially growing E. coli TG1 cells, before plating and titration on 2xTY agar plates containing 2% glucose and 0.1 mg/ml ampicillin.
Screening of single clones from selected populations by analysis of binding to TNF
alpha in ELISA was done essentially as described in WO/0248189, except that antigen used for coat in ELISA was 5pg/ml TNF.
A specific TNF alpha binder, called TN3-2, was isolated from the second round of selection (Table 4).
Secondary library construction and affinity driven selection It was investigated whether the TNF affinity of TN3-2 could be improved by introducing new sequence variation to TN3-2. For the construction of a library of TN3-2 mutants, the TN3-2 clone was used as a template and subjected to new randomization in loop 4 using the oligonucleotides TN-lib2-tpfo (SEQ ID N0:101 ) and TN-lib3-tpfo (SEQ
ID
N0:100) (Lib. TN3-2 loop4 r). The library construction was done essentially as described in WO/0248189.
The TN3-21oop4r library was used in 3 rounds of affinity driven selection with decreasing concentrations of biotinylated TNF (100 ng/ml to 0.1 ng/ml).
Selection was done as described above. Screening for positive clones was done as described above.
Results The sequence of the parental clone TN3-2 was different from tetranectin in loop 1 (Tetranectin amino acids nos. 116-122) and in loop 4 (Tetranectin amino acids nos.
146-149). After three rounds of affinity driven selection on the TN3-21oop4r library, positive clones were identified by ELISA analysis, and 45 out of 48 clones were shown to bind TNF alpha. Loop 1 and loop 4 sequences of a selection of the identified TNF
alpha binding clones together with their corresponding SEQ ID NOs are shown in Table 4 (TN3-2-B, TN3-2-C, TN3-2-D).

Example 10 Affinity measurements of trimerised CTLD binders for TNF
The DNA inserts encoding the monomeric CTLD TNF alpha binders isolated as described in Example 7 were subcloned into E. coli pBAD expression vector (Invitrogen Corp., USA). The recombinant monomer TNF alpha binders were expressed in E. coli and purified from periplasm according to the manufactures instructions. Purified monomers were dialysed into 10 mM Tris pH 8.0, 150 mM
NaCI, 2 mM CaCl2 before analysis on BiaCore.
In order to express the trimeric format of the TNF alpha binders, appropriate DNA
inserts encoding the TNF alpha binders (from Example 7) were cleaved with the restriction endonucleases Bgl II and Mun I, and the loop 1 and 4 containing DNA
fragment subcloned into Bgl II Mun I restricted E. coli pT7H6FX-htlec DNA (as outlined in WO 02/48189, Example 1 and Fig. 5).
The recombinant trimeric TNF alpha binders were expressed in E. coli and purification of the unfolded fusion protein derivatives were performed essentially as described in WO 94/18227, Example 9.
Briefly, refolding of the TNF alpha binders were performed by loading the fusion proteins on Ni2+-charged nitrilotriacetic acid (NTA) columns in 8 M urea, 50 mM Tris-HCI pH 8.0, 500 mM NaCI, 5 mM 2-mercaptoethanol. After being loaded, the columns were subjected to a cyclic refolding procedure. Refolding buffers used were:
renaturation buffer A (50 mM Tris-HCI pH 8.0, 500 mM NaCI, 2 mM CaCl2, 2 mM
reduced glutathione, and 0.2 mM oxidized glutathione) and denaturing buffer B
(8 M
urea, 50 mM Tris-HCI pH 8.0, 500 mM NaCI, 2 mM CaCl2, 3 mM reduced glutathione).
Refolded fusion proteins were eluted from the columns by 50 mM Tris-HCI pH
8.0, 500 mM NaCI, 10 mM EDTA and the fusion proteins were cleaved with bovine blood coagulation factor Xa (Protein Engineering Technology, Aarhus, Denmark) at 1:100 (w/w) at 4°C overnight. The cleaved proteins were taken into a 8 M
urea, 25 mM
sodium acetate buffer (pH 5), 50 mM NaCI, 1 mM Tris-HCI buffer by gel filtration on Sephadex G25 and loaded on 10 ml SP-Sepharose columns (Amersham Biosciences) and gradient-eluted from 50 mM to 500 M NaCI over 20 column volumes. Fractions containing cleaved and monomeric protein, as judged by non-reducing SDS/PAGE
analysis, were pooled and the buffer was exchanged to 10 mM Tris pH 8.0, 150 mM
NaCI, 2 mM CaCl2 by gel filtration on PD10 columns (Amersham Biosciences).
Surface plasmon resonance (SPR) binding analysis was performed on a BIAcore 3000 instrument (BiaCore, Sweden). TNF alpha capture antibody (AHC3712, Biosource International) to be immobilized was dissolved in 10 mM NaAcetate pH
receptor and thereby, due to high local concentration of the receptors on the cell surface, initiate the further recruitment of TNF receptors and by that signal transduction. This problem is illustrated in Figure 2.
The same problem is seen with the TNF binder Infliximab. Each Infliximab molecule is only capable of binding one receptor binding site (subunit) of a given TNF
molecule, hence leaving out two open receptor binding sites. These open receptor binding sites may subsequently associate with corresponding free receptors, resulting in further recruitment of TNF receptors and receptor signalling.
It has now been found by the present inventors, that the above technical problems may be overcome by the provision of a fusion protein (protomer) which is constructed as a fusion of a binding unit (binder) for trimeric cytokines to a trimerising domain. The fusion protein of the present invention is, as a trimeric protein, capable of forming a 1:1 complex with a trimeric cytokine and preferably at the same time effectively binding all three receptor binding sites of the trimeric cytokines, whereby no receptor binding sites are left open, and is therefore able to inhibit docking of the cytokine to the cell surface.
Thus, there is now provided a fusion protein which has the advantage of being capable of more effectively inhibiting and neutralising the biological activity of trimeric cytokines as compared to presently known trimeric cytokine antagonists. A further advantage of the fusion protein according to the invention is that when applied as a medicament, less amount of the fusion protein is required in order to obtain a therapeutic effect, as compared to the presently know binders for trimeric cytokines.
Summary of the invention Accordingly, the invention relates in a first aspect to a trimeric polypeptide comprising three monomers, each of said monomers comprising a specific binding member capable of binding a trimeric cytokine, and each of said monomers comprising a trimerising domain.
In a further aspect there is provided a pharmaceutical composition comprising the trimeric polypeptide according to the invention.
In a still further aspect, the invention pertains to a method of treating a subject having a pathology mediated by a trimeric cytokine such as tumour necrosis factor, by administering an effective amount of the trimeric polypeptide according to the invention to the subject, Finally, there is provided a method for the preparation of the trimeric polypeptide according to invention, and an assay method for detecting a trimeric polypeptide cytokine in a sample.
Detailed disclosure of the invention In one aspect, the present invention provides trimeric binders which are capable of binding to trimeric cytokines, preferably in a manner such that upon binding, all receptor binding sites of the trimeric cytokine are substantially blocked and/or neutralised, and hence the potential biological activity of the trimeric cytokine is suppressed or neutralised. Accordingly, there is provided a trimeric polypeptide comprising three monomers, wherein each of the monomers comprise a specific binding member which is capable of binding a trimeric cytokine, and wherein each of the monomers comprise a trimerising domain.
In the present context, the term "trimeric cytokine" refers to small proteins and fragments thereof, which are produced and secreted by a cell, and which elicit a specific response in a cell which has a receptor for that cytokine, e.g. by affecting the growth, division and/or function of the cell. The term "trimeric" is used herein to describe that the cytokines according to the invention occur as multi-subunit complexes containing three subunits, preferably three identical subunits (homotrimer).
Typical examples of such trimeric cytokines include Macrophage migration inhibitory factor (MIF) and cytokines within the tumour necrosis factor ligand super family (TNFLSF). Presently, as mentioned above, the TNF ligand super family has at least 17 recognised ligands which all share a conserved trimeric C-terminal domain known as the "TNF homology domain" (THD), which is responsible for receptor binding.
The sequence identity of this trimeric domain is approximately 20-30% between TNF
family members. The THD is a 150 amino acid long sequence containing a conserved framework of aromatic and hydrophobic residues which is illustrated in Figure 2 in Bodmer et al. 2002, TRENDS in Biochemical Sciences 27(1 ), pp. 19-26.
Accordingly, in the present context a "member of the Tumor necrosis factor ligand superfamily" is intended to mean a trimeric protein comprising the TNF homology domain, THD.
Presently known trimeric cytokines within the TNF ligand super family are listed below in Table 1, together with synonyms and their corresponding Genbank ID
(GenBank, National Center for Biotecnology Information;
http://www.ncbi.nlm.nih.gov/Genbank).
The nomenclature for the TNF ligand superfamily as used herein follows the official TNF superfamily (TNFSF) nomenclature which may be found at http://www.gene.ucl.ac.uk/nomenclature/genefamilyltnftop.html.

Accordingly, in one useful embodiment of the invention the trimeric polypeptide according to the invention is capable of binding a trimeric cytokine which is a member of the Tumor necrosis factor ligand superfamily selected from LTA; TNF ;LTB;
TNFSF4; TNFSFS; TNFSF6; TNFSF7; TNFSFB; TNFSF9; TNFSF10; TNFSF11;

The term "specific binding member", as used herein, refers to a member of a pair of molecules which have binding specificity for one another. The members of a specific binding pair may be naturally derived or wholly or partially synthetically produced. One member of the pair of molecules has an area on its surface, or a cavity, which specifically binds to and is therefore complementary to a particular spatial and polar organisation of the other member of the pair of molecules. Thus the members of the pair have the property of binding specifically to each other. Examples of types of specific binding pairs are antigen-antibody, biotin-avidin, hormone-hormone receptor, ligand-ligand receptor, enzyme-substrate. Other examples of specific binding pairs include, carbohydrates and lectins, complementary nucleotide sequences (including probe and capture nucleic acid sequences used in DNA hybridization assays to detect a target nucleic acid sequence), complementary peptide sequences including those formed by recombinant methods, effector and receptor molecules, enzyme cofactors and enzymes, enzyme inhibitors and enzymes, and the like. Furthermore, specific binding pairs can include members that are analogues or fragments of the original specific binding member.
In useful embodiments, the specific binding members capable of binding a trimeric cytokine, provides the trimeric polypeptide according to the invention with a binding affinity (Kd) for the trimeric cytokine that preferably is 1 x 10-$ M or less determined by surface plasmon resonance. In other useful embodiments, the Kd value is less than 1 x 10-9 M, 1 x 10-'° M, 1 x 10-" M, 1 x 10-'2 M, 1 x 10-'3 M, 1 x 10-'4 M, or even less than 1 X 1 O-'S M. In further useful embodiments, the K-off rate for the trimeric polypeptide according to the invention is less than 1 x 10-3 S-', such as less than 1 x 10-4 S'', including less than 1 x 10-5 S-', and even less than 1 x 10-6 S-' determined by surface plasmon resonance. The term "K-off', as used herein, is intended to refer to the off rate constant for dissociation of a specific binding member from the specific binding member/trimeric cytokine complex. The term "surface plasmon resonance", as used herein, refers to an optical phenomenon that allows for the analysis of real-time biospecific interactions by detection of alterations in protein concentrations within a biosensor matrix, for example using the BIAcore system (Pharmacia Biosensor AB, Uppsala, Sweden). For further descriptions, see Example 10.
As mentioned above, it is preferred that the trimeric cytokine binder according to the invention at least partially or fully blocks, inhibits, or neutralises a biological activity of a trimeric cytokine. As used herein, the expression "neutralises" or "neutralisation"
means the inhibition of or reduction in a biological activity of a trimeric cytokine as measured in vivo or in vitro.
In useful embodiments the specific binding member is a polypeptide derived from a member of the Tumor necrosis factor receptor superfamily. Presently, at least receptors within the Tumor necrosis factor superfamily are known, and listed below in Table 2 together with their synonyms and their corresponding Genbank ID

Thus, in useful embodiments the specific binding member derived from a receptor within the Tumor necrosis factor superfamily is selected from the receptors TNFRSF1A, TNFRSF1B, LTBR, TNFRSF4, TNFRSFS, TNFRSF6, TNFRSF6B, TNFRSF7, TNFRSFB, TNFRSF9, TNFRSF10A, TNFRSF10B, TNFRSF10C, TNFRSF10D, TNFRSF11A, TNFRSF11B, TNFRSF12, TNFRSF12L, TNFRSF13B, TNFRSF13C, TNFRSF14, NGFR, TNFRSF17, TNFRSF18, TNFRSF19, TNFRSF19L, TNFRSF21, TNFRSF22, and TNFRSF23. However, it is also contemplated that further useful receptors may be identified within this protein family, and hence further functional specific binding members.
In a useful embodiment, the specific binding member is derived from the TNF
receptors TNFRSF1A (TNFrI, p55 receptor) and/or TNFRSF1 B (TNFrI I, p75 TNF
receptor). Especially the TNFRSF1 B receptor and subunits thereof has proven to be effective for specifically binding and neutralising TNF. As an example, the TNF binding protein Eternacept is a fusion protein made up of the extracellular domain of the TNFRSF1 B receptor, i.e. a subunit of the TNFRSF1 B receptor. Accordingly, in specific embodiments, the trimeric polypeptide according to invention includes a specific binding member which is a subunit or fragment of the TNFRSF1 B receptor (TNFrII), such as the TNFRSF1 B receptor fragments disclosed in US 5,712,155. Thus, in useful embodiments the specific binding member is a polypeptide comprising an amino acid sequence selected from TNFRSF1B 1-235 (SEQ ID N0:76), TNFRSF1B 1-185 (SEQ
ID N0:77), TNFRSF1B 1-163 (SEQ ID N0:78) and TNFRSF1B 1-142 (SEQ ID
N0:79).
In further useful embodiments, as disclosed in following examples, the specific binding member may be one or more fragments of the TNFRSF1 B receptor (TNFrII) and combinations of such fragments, such as a polypeptide comprising an amino acid sequence encoded by a DNA sequence selected from TNFRSF1 B D1 D2 (SEQ ID
N0:13), TNFRSF1 B D1 D2, 1/6 (SEQ ID N0:15), TNFRSF1 B D1 D2 1/4 (SEQ ID
N0:17), TNFrII D1 D2, 1/3 (SEQ ID N0:19), TNFRSF1 B D1 D2, 1/2 (SEQ ID N0:21 ), TNFRSF1 B D1 D4 (SEQ ID N0:23), TNFRSF1 B D2 (SEQ ID N0:25), TNFRSF1 B D2, 1/6 (SEQ ID N0:26), TNFRSF1B D2, 1/4 (SEQ ID N0:27), TNFRSF1B D2, 1/3 (SEQ
ID N0:28), TNFRSF1B D2, 1/2 (SEQ ID N0:29) and TNFRSF1B D2D4 (SEQ ID
N0:30).
In accordance with the invention, the specific binding member capable of binding a trimeric cytokine may also be an antibody or an antibody fragment. In the present context, the term "antibody" is used to describe an immunoglobulin whether natural or partly or wholly synthetically produced. As antibodies can be modified in a number of ways, the term "antibody" should be construed as covering any specific binding member or substance having a binding domain with the required trimeric cytokine specificity. Thus, this term covers antibody fragments, derivatives, functional equivalents and homologues of antibodies, including any polypeptide comprising an immunoglobulin binding domain, whether natural or wholly or partially synthetic.
Chimeric molecules comprising an immunoglobulin binding domain, or equivalent, fused to another polypeptide are therefore included. The term also covers any polypeptide or protein having a binding domain which is, or is homologous to, an antibody binding domain, e.g. antibody mimics. These can be derived from natural sources, or they may be partly or wholly synthetically produced. Examples of antibodies are the immunoglobulin isotypes and their isotypic subclasses;
fragments which comprise an antigen binding domain such as Fab, scFv, Fv, dAb, Fd; and diabodies.
US 6,451,983 B2 describes antibodies for human tumour necrosis factor which are i.a.
capable of neutralising the biological activity of TNF. In particular, US
6,451,983 B2 provides antibodies and fragments thereof which are capable of binding to mature human TNF (SEQ ID N0:80) within certain specific topographic regions.
Accordingly, in useful embodiments of the present invention, the specific binding member is an antibody or fragment thereof which is capable of binding mature human TNF (SEQ
ID
N0:80) in at least one region selected from the regions consisting of amino acid residues 1-18, 1-20, 1-26, 1-30, 12-22, 22-31, 22-40, 36-45, 49-97, 49-98 , 56-79, 58-65, 69-97, 70-87, 76-90, 96-105, 105-128, 108-128, 110-127, 115-125, 117-128, 157, 135-155, 136-153, 138-149, 141-153 and 146-157.
US 6,451,983 B2 further provides specific monoclonal antibodies which may be useful in the present invention. Accordingly, the specific binding member capable of binding human TNF may be an antibody or antibody fragment selected from MAb 1 (ECACC
89080301 ), MAb 21 (ECACC 90012432), MAb 25 (ECACC 89121401 ), MAb 32 (ECACC 89080302), MAb 37 (ECACC 89080303), MAb 42 (ECACC 89080304), MAb 47 (ECACC 89121402), MAb 53 (ECACC 90012433) and MAb 54 (ECACC
89083103), wherein ECACC refers to European Collection of Animal Cell Cultures.
Further examples of useful antibodies include the humanised antibody D2E7 as disclosed in US 6,090,382 and the humanised antibody fragment CDP 870 as disclosed in WO/00194585.
In specific embodiments, the specific binding members of the present invention may comprise antibody analogues or artificial antibodies such as e.g. a protein having the scaffold structure of C-type lectin-like domains (CTLD) as disclosed in WO/0248189.
As will be apparent from the following Examples, useful human tetranectin based CTLD antibody analogues which are capable of binding TNF may be selected from TN3-2-B (SEQ ID N0:103), TN3-2-C (SEQ ID N0:104) and TN3-2-D (SEQ ID
N0:105).
An important aspect of the present invention is that the monomers of the trimeric polypeptide, in addition to the specific binding member, further comprise a trimerising domain. In the present context, the term "trimerising domain" is a peptide, a protein or part of a protein which is capable of interacting with other, similar or identical trimerising domains. The interaction is of the type that produces trimeric proteins or polypeptides. Such an interaction may be caused by covalent bonds between the components of the trimerising domains as well as by hydrogen bond forces, hydrophobic forces, van der Waals forces and salt bridges.
One example of a trimerising domain is disclosed in WO 95/31540, which describes polypeptides comprising a collectin neck region. The amino acid sequence constituting the collectin neck region may be attached to any polypeptide of choice.
Trimers can then be made under appropriate conditions with three polypeptides comprising the collectin neck region amino acid sequence.
In a presently preferred embodiment, the trimerising domain is derived from tetranectin, and more specifically comprises the tetranectin trimerising structural element (hereafter termed TTSE) which is described in detail in WO 98/56906.
The amino acid sequence of TTSE is shown in SEQ ID N0:81. The trimerising effect of TTSE is caused by a coiled coil structure which interacts with the coiled coil structure of two other TTSEs to form a triple alpha helical coiled coil trimer which is exceptionally stable even at relatively high temperatures. The term TTSE is also intended to embrace variants of a TTSE of a naturally occurring member of the tetranectin family of proteins, variants which have been modified in the amino acid sequence without adversely affecting, to any substantial degree, the capability of the TTSE to form alpha helical coiled coil trimers. Thus, the trimeric polypeptide according to the invention may comprise a TTSE as a trimerising domain, which comprises a sequence having at least 68% amino acid sequence identity with the sequence of SEQ ID NO SEQ ID N0:81, such as at least 75%, including at least 87%, such as at least 92%. In accordance herewith, the cystein residue No. 50 of the TTSE (SEQ ID N0:81 ) may advantageously be mutagenised to serine, threonine, methionine or to any other amino acid residue in order to avoid formation of an unwanted inter-chain disulphide bridge, which could lead to unwanted multimerisation.
In a further embodiment, the TTSE trimerising domain (SEQ ID N0:81 ) may be modified by (i) the incorporation of polyhistidine sequence and/or a cleavage site for the Blood Coagulating Factor Xa, (ii) replacing Cys 50 with Ser, and (iii) by including a C-terminal KGS sequence.
Several examples of different trimeric polypeptides in accordance with the invention are provided in the following in examples, in which the above TTSE trimerising domain has been applied. These includes i.a. the CTLD based TNF binding units TN-2-B
(SEQ
ID N0:106), TN-2-C (SEQ ID N0:108) and TN-2-D (SEQ ID N0:107), and the trimerised human TNFRII fragment AD1 D4-GSS-110 (SEQ ID N0:109).
In accordance with the invention, the specific binding member may either be linked to the N- or the C-terminal amino acid residue of the trimerising domain.
However, it is also envisaged that in certain embodiments it may be advantageous to link a specific binding member to both the N-terminal and the C-terminal of the trimerising domain of the monomer, and thereby providing a trimeric polypeptide comprising six specific binding members capable of binding a trimeric cytokine.
It will be appreciated that a flexible molecular linker optionally may be interposed between, and covalently join, the specific binding member and the trimerising domain.
In certain embodiments, the linker is a polypeptide sequence of about 1-20 amino acid residues. The linker may be less than 10 amino acids, most preferably, 5, 4, 3, 2, or 1.
It may be in certain cases that 9, 8, 7 or 6 amino acids are suitable. In useful embodiments the linker is essentially non-immunogenic, not prone to proteolytic cleavage and does not comprise amino acid residues which are known to interact with other residues (e.g. cystein residues).
The trimeric polypeptide of the present invention may be expressed in any suitable standard protein expression system by culturing a host transformed with a vector encoding the trimeric polypeptide under such conditions that the trimeric polypeptide is expressed. Preferably, the expression system is a system from which the desired protein may readily be isolated and refolded in vitro. As a general matter, prokaryotic expression systems are preferred since high yields of protein can be obtained and efficient purification and refolding strategies are available. Thus, it is well within the abilities and discretion of the skilled artisan, without undue experimentation, to choose an appropriate or favourite expression system. Similarly, once the primary amino acid sequence for the trimeric polypeptide of the present invention is chosen, one of ordinary skill in the art can easily design appropriate recombinant DNA
constructs which will encode the desired proteins, taking into consideration such factors as codon biases in the chosen host, the need for secretion signal sequences in the host, the introduction of proteinase cleavage sites within the signal sequence, and the like.
These recombinant DNA constructs may be inserted in-frame into any of a number of expression vectors appropriate to the chosen host. The choice of an appropriate or favourite expression vector is, again, a matter well within the ability and discretion of the skilled practitioner. Preferably, the expression vector will include a strong promoter to drive expression of the recombinant constructs. Finally, the trimeric polypeptide may be isolated using suitable standard procedures well known in the art, and optionally subjected to further processing such as e.g. lyophilization.
The trimeric polypeptide according to the invention may be used for the preparation of a pharmaceutical composition by any suitable method well known in the art. The composition may together with the trimeric polypeptide, comprise one or more acceptable carriers therefore, and optionally other therapeutic ingredients.
The carriers must be acceptable in the sense of being compatible with the other ingredients and not deleterious to the recipient thereof. In general, methods for the preparation of pharmaceutical compositions include the step of bringing into association the active ingredient and a carrier.
The therapeutic application of the present invention comprises the treatment of a disease or disorder in an animal, by administering a therapeutically effective amount of the trimeric polypeptide according to the invention to an animal in need thereof. As mentioned above, trimeric cytokines, and in particular trimeric cytokines of the TNF
ligand super family, are known to be pleiotropic polypeptides that act as intercellular signal transduction molecules by i.a. controlling and coordinating immune and inflammatory responses. Thus, it will be appreciated that the trimeric polypeptide of the present invention may be applicable for the treatment of wide range of disorders and diseases mediated by trimeric cytokines, including inflammatory diseases, autoimmune disorders, immune disorders, infections, malignancies, and neurogenerative diseases.
In one useful embodiment the disease is a pathology mediated by tumor necrosis factor, such as rheumatoid arthritis, psoriasis and Crohn's disease.
The trimeric polypeptide of the present invention may be directly administered to the animal by any suitable technique, including parenterally, and can be administered locally or systemically. The specific route of administration depends, e.g., on the medical history of the animal. Examples of parenteral administration include subcutaneous, intramuscular, intravenous, intraarterial, and intraperitoneal administration.
The animals potentially treatable by the trimeric fusion protein herein include mammals such as a human.
Finally, the present invention provides an assay method for detecting a trimeric polypeptide cytokine in a sample which comprises (i) contacting the sample with a trimeric polypeptide according to the invention, and (ii) detecting the binding of the trimeric polypeptide to the trimeric cytokine.
The invention will now be described by way of illustration in the following non-limiting examples and figures.
Description of the figures Figure 1 shows the binding of a trimeric cytokine within the Tumour Necrosis Factor Super Family to a corresponding cell bound monomeric receptor, which initiates the further recruitment of two more cytokine receptors resulting in the formation of a hexameric cytokine-receptor signalling unit.
Figure 2 shows the binding of a bivalent binder to a trimeric cytokine within the Tumour Necrosis Factor Super Family (TNFSF), which forms a 1:1 complex with the trimeric cytokine. When the bivalent binder binds to the trimeric TNFSF
cytokine, only two out off three possible receptor binding sites are occupied by the bivalent binder molecule, and the third receptor binding site is left open. This implies that the open trimeric cytokine receptor binding site may associate with a cell surface trimeric cytokine receptor and thereby, due to high local concentration of the receptors on the cell surface, initiate the further recruitment of trimeric receptors and thereby signal transduction.
Figure 3 shows a binder for trimeric cytokines which is capable of forming a 1:1 complex with a trimeric cytokine and at the same time effectively binding all three receptor binding sites of the trimeric cytokine, whereby no receptor binding sites are left open. The docking of the cytokine to the cell surface is blocked, and hence no signal transduction will occur.
Figure 4 shows inhibition of TNF alpha mediated cytotoxicity in a murine fibroblast cell line L929 assay at two different fixed TNF alpha concentrations (1.0 ng/ml and 0.1 ng/ml) for the trimerised receptorfragment D1 D4GSS110 Trip in 10-fold dilutions.

Example 3 Production, refolding and purification of trimerised TNFRII fragment AD1 D4-GSS-110-TripB
Construction of the T7 RNA polymerise dependent expression plasmid pT7D1 D4GSS110 (expressing the TNFRII derivative AD1 D4-GSS-110-TripB) is described above in Example 2.
Trimerised human TNFRII fragment AD1 D4-GSS-110 (SEQ ID N0:109) was produced by growing and expressing the plasmid pT7AD1 D4-GSS-110 in E. coli BL21 cells in a medium scale (6 x 1 litre) as described by Studier and Moffat, J. Mol. Biol., 189:
113-130, 1986. Briefly, exponentially growing cultures at 37°C were at OD600 0.8 infected with bacteriophage ~-CE6 at a multiplicity of approximately 5.
Cultures were grown at 37°C for another three hours before cells were harvested by centrifugation.
Cells were lysed by osmotic shock and sonification and total cellular protein extracted into phenol (adjusted to pH 8 with Trisma base). Protein was precipitated from the phenol phase by addition of 2.5 volumes of ethanol and centrifugation. The protein pellet was dissolved in a buffer containing 6 M Guanidinium chloride, 50 mM
Tris-HCI
pH 8 and 50 mM dithioerythriol. Following gel filtration on Sephadex G-25 (Amersham Biosciences) into 8 M Urea, 0.5 M NaCI, 50 mM Tris-HCI pH 8, and 5 mM 2-mer-captoethanol the crude protein preparation was applied to Ni2+ activated NTA-agarose (Qiagen, Germany) columns for purification (Hochuli et al., 1988) of the fusion proteins and, while immobilised on the column, to undergo the cyclic folding procedure as previously described in WO 94/18227.
All buffers prepared for liquid chromatography were degassed under vacuum prior to addition of reductant and/or use.
Upon application of the crude protein extracts on the Ni2+NTA-agarose column, the fusion protein, AD1 D4-GSS-110, was purified from the majority of coli and ~
phage proteins by washing with one column volume of the loading buffer followed by 6 M
Guanidinium chloride, 50 mM Tris-HCI, and 5 mM 2-mercaptoethanol until the optical density (OD) at 280 nm of the column eluate was stable.
The fusion proteins were refolded on the Ni2+NTA-agarose column using a gradient manager profile as described in Table 1 and 0.5 M NaCI, 50 mM Tris-HCI pH 8, and 2 mM/0.2 mM reduced/oxidized gluthatione as buffer A and 8 M urea, 0.5 M NaCI, mM Tris-HCI pH 8, and 3 mM reduced gluthatione as buffer B.
After completion of the cyclic folding procedure the AD1 D4-GSS-110 fusion protein was eluted from the Ni2+NTA-agarose columns with a buffer containing 8 M Urea, 0.5 M
NaCI, 50 mM Tris-HCI, and 10 mM EDTA pH 8.
Monomeric AD1 D4-GSS-110 fusion proteins were purified from di-mer and higher order multimers by ion exchange chromatography on S- and Q-Sepharose (AmershamBiosciences): The fusion protein eluted by the elution buffer (approximately 80 % of the fusion protein material) was gelfiltrated into a buffer containing 8 M Urea, mM Tris-HCI pH 8.0 and 25 mM NaCI on Sephadex G-25 and applied onto the S-Sepharose ion exchange column. The non-binding protein in the "run through"
fractions were directly loaded onto the Q-Sepharose column. Monomeric AD1 D4-GSS-110 fusion proteins were eluted from the Q-Sepharose column with a liner gradient from 8 M Urea, 25 mM NaCI, 10 mM Tris-Hcl pH 8 to 8 M Urea, 300 mM NaCI, 10 mM
Tris-Hcl pH 8 over 10 column volumes. Monomeric AD1 D4-GSS-110 fusion protein eluted in the very beginning of the gradient, whereas dimers and higher order multimers eluted later. Fractions containing the monomeric fusion protein were renatured and trimerised by gelfiltration into a buffer containing 10 mM HEPES
pH 7.4 and 125 mM NaCI.

The murine fibroblast cell line L929 (ECACC no.: 85011425) was used to measure TNF alpha mediated cytotoxicity. Cells were maintained in RPMI 1640 liquid medium (Biowhittaker, UK) supplemented with 10% FBS, and antibiotics (100 U/ml penicillin, 100 Ng/ml streptomycin). The cells were plated into 96-well flat-bottom microtiter plates (NUNC, Roskilde, Denmark) at 3 x 105 cells/ml and 75 NI/well of complete RPMI
1640 medium and cultured overnight at 37°C in 5% C02. Recombinant human TNF
alpha (rhTNFa, RD Systems, UK) (1 ng/ml and 0.1 ng/ml) was incubated with various concentrations (10-fold dilutions) of trimerised receptorfragment (AD1 D4-GSS-110) in complete RPMI 1640 medium supplemented with 2 pg/ml actinomycin D (Sigma) for hr at 37°C in 5% C02. Hereafter, 75 NI/well of the TNF-alpha/trimerised receptorfragment mixtures were added to the cell culture for overnight incubation at 37°C in 5% C02. Each concentration of the TNF-alpha / receptorfragment mixture was tested in triplicate. Cell proliferation was determined using MTT (3-[4,5-dimethyl-thiazol-2-yl]-2,5-di-phenyl-tetrazolium bromide) as part of the CeIITiter 96 Non-Radioactive Cell Proliferation Assay Kit (Promega). For the preparation of reagents sufficient for one 96 well plate containing cells cultured in a 150 pl volume, 3.0 ml of MTS Solution was added to 150 NI of PMS. 30 NI/well of the combined MTS/PMS
solution was added and the plates were incubated 1-4 hr at 37°C in 5%
C02 before recording the absorbance at 492 nm using an ELISA plate reader. Controls of TNF
alpha with the cells, cells alone and buffer control were also included in each assay.
The result of the experiment is summarised in Fig. 4. The cytotoxic effect of TNF alpha was significantly inhibited in the presence of the highest concentration of 110 thus demonstrating biological activity of the compound.

To prepare the above fusion proteins H6FXD2E7tripB, H6FXD2E7G4StripB, H6FXTripAD2D7TripA and H6FxTripAG4SD2E7, the plasmids pT7H6FXD2E7tripB, pT7H6FXD2E7G4StripB, pT7H6FXTripAD2D7TripA and pT7H6FxTripAG4SD2E7 is grown in small scale (1 litre; 2xTY medium, 5 mM MgS04 and 100 4 g ampicillin) in E.
coli BL21 cells, as described by Studier et al. (1990). Exponentially growing cultures at 37°C are at OD600 0.8 infected with bacteriophage lambda CE6 at a multiplicity of approximately 5. Cultures are grown at 37°C for another three hours and the cells harvested by centrifugation. Cells are re-suspended in 50 ml of 0.5 M NaCI, 50 mM
Tris-HCI pH 8, and 1 mM EDTA pH 8. Phenol (50 ml adjusted to pH 8) is added to each and the mixtures are sonicated to extract total protein. After clarification by centrifugation (25 minutes at 10.000 g) crude protein fractions are precipitated from the phenol phases by addition of 2.5 volumes of ethanol and centrifugation.
Protein pellets are dissolved in a buffer (15-25 ml) containing 6 M guanidinium chloride, 50 mMTris-HCI pH 8 and 0.1 M dithioerythriol. Following gel filtration on Sephadex G-25 (Pharmacia, Sweden) into 8 M Urea, 1 M NaCI, 50 mM Tris-HCI pH 8 and 10 mM 2-mercaptoethanol, the crude protein preparations are applied to Ni activated NTA-agarose columns (75 ml column volume) for purification (Hochuli et al., 1988).
Washing buffer (6 M guanidine-HCI, 50 mM Tris-HCI pH 8 and 10 mM 2-mercaptoethanol) is then flowed through the columns until stable baselines are obtained.
Virtually pure fusion proteins are then eluted by applying a pH gradient to each column (1000 ml gradient in 8 M urea and 10 mM 2-mercaptoethanol obtained by linear (per volume) mixing of solutions containing 50 mM sodium di-hydrogenphosphate (pH 5 buffer) and 50 mM di-sodium hydrogenphosphate (pH 8 buffer).
In preparation for in vitro refolding by the method of Thogersen et al. (WO
94/18227) 20 mg of each purified fusion protein are mixed in suspensions in refolding "buffer B"
(described below) with aliquots of suspensions of Ni2+ activated NTA-agarose matrix sufficient to generate columns of about 75 ml packed bed volume. Each fusion protein is then subjected to the iterative refolding procedure as described for plasminogen kringle 4 in WO 94/18227, except that refolding of the scFv containing fusion proteins is carried out at 10°C using a buffer containing 0.5 M NaCI, 50 mM Tris-HCI pH 8, 2 mM glutathione and 0.2 mM oxidized glutathione as "buffer A" and a buffer containing 8 M urea, 1 M NaCI, 50 mM Tris-HCI pH 8 and 2 mM glutathione as "buffer B".
After completion of the refolding procedure each column is washed with 300 ml buffer containing 0.5 M NaCI and 50 mM Tris-HCI pH 8 to wash away glutathione. The refolded fraction of each protein is then eluted from the NTA-agarose in 20 mM
EDTA, 0.5 M NaCI and 50 mM Tris-HCL pH 8 to the elution buffer. After addition of solid urea to achieve a final concentration of about 8 M to each protein sample and dilution or dialysis to reduce NaCI concentrations to below 5 mM, final purification of each correctly folded fusion protein product is then accomplished by ion exchange chromatography (S-Sepharose, Pharmacia, 1,6 (i.d.) by 90 centimeter column in a buffer containing 8 M urea, 5 mM Tris-HCI (from 1 M stock solution at pH 8) and 25 mM sodium acetate (from 1 M stock solution at pH 5), eluted at 2 ml/min).
After dialysis against aqueous buffers (e.g. phosphate buffered saline) each pure and correctly refolded fusion protein is recovered in yields of 2-6 mg per litre of culture grown.

The design and cloning of the binder is outlined in the following:

N0:74) into a BamH I and Kpn I cut vector, PT7H6-bktripB using standard procedures.
Outlines of the resulting the nucleotide sequence of FXTNFRSF13C, is given as SEQ

Example 9 Isolation and construction of trimerised CTLD binders for TNF
The scaffold structure of Tetranectin (SEQ ID N0:96) C-type lectin-like domains (CTLD), as previously disclosed in WO/0248189, was used for the isolation and construction of a trimeric binding units for the trimeric cytokine TNF (TNF
alpha). The design and cloning of the binding units is outlined in the following:
Library construction and primary selection Phage display was used to isolate TNF CTLD binders. The phage display libraries used were based on the monovalent CTLD format of tetranectin (SEQ ID N0:97).
The combinatorial library PhtCTLD-Ib003 (WO/0248189, Example 5) and a variant of this library made essential as PhtCTLD-Ib003, but including two additional randomised oligonucleotides for loop 1: TN-lib3-tprev, randomised in tetranectin (SEQ ID
N0:98) amino acid residue positions 116-122 and TN-lib2-tprev (SEQ ID NO: 99) and 2 additional oligonucleotides for loop 4: TN-lib3-tpfo, randomised in position (SEQ ID N0:100) and TN-lib2-tpfo (SEQ ID N0:101 ) in the assembly reaction.
Two rounds of selection were performed using approximately 1 x 10'2 phage as input and Ng/ml biotinylated-TNF in the first round of panning and 1 Ng/ml in the second.
The selections were performed as follows: 20 NI streptavidin-coated paramagnetic beads (Dynal) were washed two times in 1 ml PBS (PBS, 0.2 g KCI, 0.2 g KH2P04, 8 g NaCI, 1.44 g Na2HP04, 2H20, water to 1 I, and adjusted to pH 7.4 with NaOH), and blocked in 3% non fat dried milk for one hour at room temperature. 250 NI
preblocked phage in 3% non fat dried milk/PBS were mixed with 250 NI of soluble biotinylated TNF, and allowed to incubate at 37°C for 30 minutes. After washing the streptavidin beads once in PBS, 0.1 % Tween 20 and twice in PBS, these were added to the reaction to capture antigen-bound phage. The beads were extensively washed with PBS, 0.1 % Tween 20 and PBS, and antigen bound phage were eluted from the beads with 200 NI 50 mM dithiothreitol for 30 min at room temperature. Eluted phages were reinfected in exponentially growing E. coli TG1 cells, before plating and titration on 2xTY agar plates containing 2% glucose and 0.1 mg/ml ampicillin.
Screening of single clones from selected populations by analysis of binding to TNF
alpha in ELISA was done essentially as described in WO/0248189, except that antigen used for coat in ELISA was 5pg/ml TNF.
A specific TNF alpha binder, called TN3-2, was isolated from the second round of selection (Table 4).
Secondary library construction and affinity driven selection It was investigated whether the TNF affinity of TN3-2 could be improved by introducing new sequence variation to TN3-2. For the construction of a library of TN3-2 mutants, the TN3-2 clone was used as a template and subjected to new randomization in loop 4 using the oligonucleotides TN-lib2-tpfo (SEQ ID N0:101 ) and TN-lib3-tpfo (SEQ
ID
N0:100) (Lib. TN3-2 loop4 r). The library construction was done essentially as described in WO/0248189.
The TN3-21oop4r library was used in 3 rounds of affinity driven selection with decreasing concentrations of biotinylated TNF (100 ng/ml to 0.1 ng/ml).
Selection was done as described above. Screening for positive clones was done as described above.
Results The sequence of the parental clone TN3-2 was different from tetranectin in loop 1 (Tetranectin amino acids nos. 116-122) and in loop 4 (Tetranectin amino acids nos.
146-149). After three rounds of affinity driven selection on the TN3-21oop4r library, positive clones were identified by ELISA analysis, and 45 out of 48 clones were shown to bind TNF alpha. Loop 1 and loop 4 sequences of a selection of the identified TNF
alpha binding clones together with their corresponding SEQ ID NOs are shown in Table 4 (TN3-2-B, TN3-2-C, TN3-2-D).

Example 10 Affinity measurements of trimerised CTLD binders for TNF
The DNA inserts encoding the monomeric CTLD TNF alpha binders isolated as described in Example 7 were subcloned into E. coli pBAD expression vector (Invitrogen Corp., USA). The recombinant monomer TNF alpha binders were expressed in E. coli and purified from periplasm according to the manufactures instructions. Purified monomers were dialysed into 10 mM Tris pH 8.0, 150 mM
NaCI, 2 mM CaCl2 before analysis on BiaCore.
In order to express the trimeric format of the TNF alpha binders, appropriate DNA
inserts encoding the TNF alpha binders (from Example 7) were cleaved with the restriction endonucleases Bgl II and Mun I, and the loop 1 and 4 containing DNA
fragment subcloned into Bgl II Mun I restricted E. coli pT7H6FX-htlec DNA (as outlined in WO 02/48189, Example 1 and Fig. 5).
The recombinant trimeric TNF alpha binders were expressed in E. coli and purification of the unfolded fusion protein derivatives were performed essentially as described in WO 94/18227, Example 9.
Briefly, refolding of the TNF alpha binders were performed by loading the fusion proteins on Ni2+-charged nitrilotriacetic acid (NTA) columns in 8 M urea, 50 mM Tris-HCI pH 8.0, 500 mM NaCI, 5 mM 2-mercaptoethanol. After being loaded, the columns were subjected to a cyclic refolding procedure. Refolding buffers used were:
renaturation buffer A (50 mM Tris-HCI pH 8.0, 500 mM NaCI, 2 mM CaCl2, 2 mM
reduced glutathione, and 0.2 mM oxidized glutathione) and denaturing buffer B
(8 M
urea, 50 mM Tris-HCI pH 8.0, 500 mM NaCI, 2 mM CaCl2, 3 mM reduced glutathione).
Refolded fusion proteins were eluted from the columns by 50 mM Tris-HCI pH
8.0, 500 mM NaCI, 10 mM EDTA and the fusion proteins were cleaved with bovine blood coagulation factor Xa (Protein Engineering Technology, Aarhus, Denmark) at 1:100 (w/w) at 4°C overnight. The cleaved proteins were taken into a 8 M
urea, 25 mM
sodium acetate buffer (pH 5), 50 mM NaCI, 1 mM Tris-HCI buffer by gel filtration on Sephadex G25 and loaded on 10 ml SP-Sepharose columns (Amersham Biosciences) and gradient-eluted from 50 mM to 500 M NaCI over 20 column volumes. Fractions containing cleaved and monomeric protein, as judged by non-reducing SDS/PAGE
analysis, were pooled and the buffer was exchanged to 10 mM Tris pH 8.0, 150 mM
NaCI, 2 mM CaCl2 by gel filtration on PD10 columns (Amersham Biosciences).
Surface plasmon resonance (SPR) binding analysis was performed on a BIAcore 3000 instrument (BiaCore, Sweden). TNF alpha capture antibody (AHC3712, Biosource International) to be immobilized was dissolved in 10 mM NaAcetate pH
5.0 and then immobilized on a CM5 BiaCore sensor chip using the Amine Coupling kit (BiaCore, Sweden).
Binding analysis was performed at a flow rate of 5 NI/min. Before loading of the protein sample, the chip was equilibrated in 10 mM Tris pH 8.0, 150 mM NaCI, 2 mM
CaCl2, 50 NM EDTA and 0.005% Surfactant P20. TNF alpha was dissolved in 10 mM Tris pH
8.0, 150 mM NaCI, 2 mM CaCl2 at 10 Ng/mL and 10 NL was injected. Aliquots (20 NI) of TNF alpha binders in monomeric or the trimeric format were injected using the KINJECT option. Five min of dissociation were allowed before the chip was regenerated with 10 mM Glycine pH 2.5. Binding of TNF alpha binders was tested at six different protein concentrations, ranging from 1 to 200 nM. Binding data were evaluated using the BIAevaluation program version 3.2 (BiaCore).
Table 5 shows the kinetic values derived from the BiaCore data. The avidity effect of trimerising the TNF alpha binders TN3-2-B, TN3-2-C, TN3-2-D is seen from the fold increase in affinity moving from the monomeric binders to the corresponding trimeric binders (TN-2-B, TN-2-C and TN-2-D).

By trimerizing the TNF alpha binders a significant gain in affinity (Kp) is obtained. For example, monomeric TN3-2-B has a very poor koff value. In contrast hereto, the trimeric version of the same CTLD binder (TN-2-B), has a koff value which is improved by over a 1000 fold. In general it can be seen that the off-rates are improved several fold by trimerisation. Moreover, the low affine parental clone TN3-2 of Example 7 could only be measured on BiaCore in its trimeric form, as the monomer had an affinity below detection limit.

Binding analysis was performed at a flow rate of 5 NI/min. Before loading of the protein sample, the chip was equilibrated in 10 mM Tris pH 8.0, 150 mM NaCI, 2 mM
CaCl2, 50 NM EDTA and 0.005% Surfactant P20. TNF alpha was dissolved in 10 mM Tris pH
8.0, 150 mM NaCI, 2 mM CaCl2 at 10 Ng/mL and 10 NL was injected. Aliquots (20 NI) of TNF alpha binders in monomeric or the trimeric format were injected using the KINJECT option. Five min of dissociation were allowed before the chip was regenerated with 10 mM Glycine pH 2.5. Binding of TNF alpha binders was tested at six different protein concentrations, ranging from 1 to 200 nM. Binding data were evaluated using the BIAevaluation program version 3.2 (BiaCore).
Table 5 shows the kinetic values derived from the BiaCore data. The avidity effect of trimerising the TNF alpha binders TN3-2-B, TN3-2-C, TN3-2-D is seen from the fold increase in affinity moving from the monomeric binders to the corresponding trimeric binders (TN-2-B, TN-2-C and TN-2-D).

By trimerizing the TNF alpha binders a significant gain in affinity (Kp) is obtained. For example, monomeric TN3-2-B has a very poor koff value. In contrast hereto, the trimeric version of the same CTLD binder (TN-2-B), has a koff value which is improved by over a 1000 fold. In general it can be seen that the off-rates are improved several fold by trimerisation. Moreover, the low affine parental clone TN3-2 of Example 7 could only be measured on BiaCore in its trimeric form, as the monomer had an affinity below detection limit.
